How does Colonel Sherburn justify shooting Boggs?

I do not really think that Colonel Sherburn ever comes
straight out and says why he has shot Boggs.  Instead, we have to infer it from what he
does say before and after.  From that, we can infer that he shoots Boggs to prove he is
a man -- he shot Boggs because Boggs insulted him and a real man does not stand for
that.

We can see this first before he shoots Boggs.  He
tells Boggs that he will not stand for his insults past 1 PM.  We can see it later when
the men come to lynch Sherburn.  He tells them that they are not men while he
is.

Between these, the implication is that men fight back
when they are insulted.  Boggs has insulted him and questioned his bravery and since he
is a man, Sherburn has killed Boggs.

In Uncle Tom's Cabin, how is the novel an example of American slavery and freedom, focusing on Tom, himself?

The subtitle of Stowe's work as, "Life Among the Lowly"
might help to bring out how the book depicts a life of enslavement and its pursuit of
freedom.  Stowe's depiction of Tom is one in which there is a spiritual dynamic at
work.  The slave is more morally righteous than those who are in the position of power. 
This significance cannot be lost on the reader.  Stowe's depiction helps to show how
American slavery is a dehumanizing experience for both those who are enslaved and those
who might profess to be free, but are actually morally enslaved.  When Legree wishes to
control Tom, he is reminded of this when Tom argues that he is more spiritually free
than Legree could ever be.  The religious faith that Tom demonstrates is something that
is even more astonishing given the cruelties and horrors he is forced to witness and
endure.  In this light, Stowe is making a direct statement about those who sincerely and
authentically believe in the power of the divine redemption.  For these individuals,
slavery is something that must be stopped for it is a tool to deny one's own spiritual
fulfillment.  The slave owners who kill Tom are morally impure and ones who require
Tom's benevolence, even when his blood is shed from their hands. In this light, freedom
is as much moral as it is political.  The issue of slavery becomes similar in that it
corrupts all that are touched by it.  Tom's journey reveals how powerful and redemptive
a spiritual identity can be when political freedoms are being
denied.

If tan x = 3/4 and tan b = 2/7 Find tan(a-b)

tana = 3/4       tan b =
2/7

We know that:

tan(a-b) =
(tan a - tanb)/(1+ tana*tanb)

Let us
substitute:

tan(a-b) = (3/4 - 2/7) / [1+
(3/4)*(2/7)]

               = (21-8)/28 / (1+
6/28)

                = 13/28 /
(34/28)

                 =
13/34

==> tan(a-b) =
13/34

How does the author create a sense of class differences throughout the play?

The officers shared the same kind of upbringing; all came
from private
schools and were highly educated. Raleigh and Stanhope both came
from
the same school and were friends outside school, often visiting one

and others homes. href="http://www.123helpme.com/search.asp?text=osborne">Osborne and Trotter
have been working in different
jobs for a while before being drafted whereas
Stanhope and Raleigh
came straight from school into the officer’s life. Not
much is known
about trotter as he is not talked about much in the story but
it is my
assumption that he was also from a private school.

Osborne and Trotter were both drafted as officers because of their

professions; they are both regarded highly in society. Stanhope and

Raleigh however were drafted as officers because of the professions of

family members, Stanhope’s father is a vicar and Raleigh’s uncle is a

senior officer, meaning he is most likely from a military background.

In terms of age of the officers, Osborne is by far the most aged of

the officers being called uncle says this quite clearly that they are

mocking his age in a friendly manner. Though Osborne is older Stanhope

is senior to him, many comments are made that Osborne should run the

company but Osborne sticks up for the young commander. Although

Stanhope is superior he values the opinion of his lower officers.

It is clear from the conversations that they all enjoy sport,

especially “Ruggers” or rugby as more commonly known. It shows that

they are all abundant in physical strength and it shows that Stanhope

has good leadership skills as he captained the cricket team in school.

Osborne however trumps him by telling Raleigh how he capped for the

England rugby team, but he swore Raleigh to secrecy so he may be lying

about that.

The officers are all fighting so that they can
get back to their
families in England and get on with their lives. They are
fighting for
their own freedom and the freedom of their families. However
Stanhope
thinks that the war has changed him so much he will never be the
same
when he gets home.

At one point Trotter takes out
some dirty postcards to show to his
fellow officers, in today’s standards
that would be no more than a
page three tabloid cut-out if not less, but
their raising has taught
them that it is wrong to treat women so
disrespectfully so they do not
look at the postcards.

The
officers all trust one another but this trust is breached on one
occasion
when Raleigh writes a letter and Stanhope demands to see it
thinking that he
may have written something about him in it which
would alert his family to
his change since he has been on the front
line.

Officer
values were the same in both the German trenches as the Allied
ones, such as
on one occasion a man lay screaming in no mans land in
clear line of German
fire and a German officer got up out of the
trench and shouted to come get
him some help and get him out of
no-mans land.

In Animal Farm, which of all animals seem to represent the point of view of the author?

I would say that Boxer probably best represents Orwell's point
of view.  I think that this is something that is brought out for a variety of reasons.  The first
is that Orwell's story ends on such a cynical note in that freedom and autonomy are not
recognized through the government.  Collective happiness is not something that is seen through
Napoleon's reign.  In the end, when the other animals cannot recognize the difference between the
humans and the pigs, it helps to bring out the fact that there is an overwhelming lack of faith
in the governmental structure.  With this in mind, I would say that Boxer becomes the ultimate
representation of how Orwell views individuals and their relationship with government.  Boxer has
blind faith in the authority structure.  Never questioning any of its ulterior motives and never
raising any voice of dissent, Boxer continues to "work harder" and do more.  In the end, after
giving everything he has to the machine of government, he is crushed by the weight of that
machine and conveniently "forgotten" so that others can continue to become the grist for
government.  This sad and cynical read is something that Orwell, himself, believed in towards the
end of his life and in the belief that human freedom and expression was not being properly
channelled in both the Communist world and the supposed "liberalized"
West.

What is the plot structure in "Just Lather, That's All"?

The situation of the story is given in the first few
paragraphs. A military man, who we come to know as Captain Torres, enters the
barbershop. The barber, who is narrating the tale, becomes very nervous, but tries to
hide his emotions from his customer:

readability="6">

Hoping to conceal my emotion, I continued
sharpening the razor.

The
complication comes when we realise that Captain Torres has just been out hunting rebel
forces. The barber confesses that he is a member of the rebel group, and therefore an
enemy of Captain Torres and implacably imposed to what he stands for. Captain Torres
also shows himself to be a cruel torturer of rebels, describing the torture of rebels as
"A fine show" as he forced all of the villagers to go past the "mutilated" hanging
bodies, which were then used for firing practice.

The
central conflict that the barber faces is whether he should take advantage of the ideal
opportunity and kill his enemy or whether he should do his job "honourably" and give him
a good shave. Note how the barber describes the options open to
him:

Murderer
or hero? My destiny depends on the edge of this
blade.

However, the
resolution comes when the barber decides that he does not want to be a murder and just
wants "lather" on his hands, and not blood. The sting in the tale at the end of the
story lies in the fact that all through the silent, internal deliberation of the barber,
Captain Torres has known that the barber is a rebel:

In the doorway he paused for a moment and said,
"They told me that you'd kill me. I came to find out. But killing isn't easy. You can
take my word for it." And he turned and walked
away.

Here are the first five terms of a sequence. 30, 29, 27, 24. 20, ... Find, in terms of n, an expression for the nth term of the sequence.How to...

The first 5 terms of the sequence are 30,
29,27,24,20.

So a1 = 30, a2 = 29, a3 = 27, a4 = 24, a5 =
20.

a2-a1 = -1, a3-a2 = -2, a4-a3 = -3, a5-a4 = -4....,
an-an-1 = n-1.

Therefore an = a1 - 1 -2 -3 - ... -(n-1) =
a1- {1+2+3+..(n-1)} = a1-n(n-1)/2.

an =
30-n(n-1)/2. 

Therefore, an = 30-n(n-1)/2 is
the expression for the nth term in terms of
n.

Tally:

a1 = 30 -(1)(0)/2 =
30

a2 = 30 -2(2-1)/2 = 29

a3 =
30 - 3(3-1)/2 = 30 -3 = 27

a4 = 30 - 4(4-1)/2 =  30 - 6 =
24

a5 = 30 -5(5-1)/2 = 30 -10 = 20.

What were some positive and negative outcomes of the French Revolution?

I think the negative outcomes were mainly short-term and the
positive ones long term. 

There is no question that the French
Revolution was needed. The Ancien Régime was brutal, denying basic human rights to the vast
majority of subjects. There was no freedom of speech or religion and the nobility could act with
impunity with no repercussions for such acts as raping female peasants or assaulting or abusing
members of the lower classes. The Roman Catholic Church had also been corrupted by its alliance
with the throne, with important posts reserved for members of the nobility rather than people
with the best qualifications, such as piety or theological knowledge. As Brettd pointed out, much
of the tax revenue, often taken from the poor and middle classes, was squandered on luxuries for
the court rather than the common good. Creating a fairer and more democratic society was a strong
and obvious positive.

The actual way in which the Revolution was
conducted, though, was harsh and brutal. The Reign of Terror (5 September 1793 – 28 July 1794)
was particularly brutal. Just as it is wrong to mistreat someone because they do not come from an
aristocratic lineage, it is equally immoral to mistreat people because they do come from an
aristocratic background. The ideal of liberty could not be realized until all people began to be
dealt with equally as individuals, not as members of classes. The eventual outcome, though, of
the current free democratic society is a strong positive.

In Don Quixote, which passages support the idea that Don Quixote's romantic dream was destroyed?

Don Quixote leaves his comfortable home to pursue a great
romantic dream. He has lost touch with reality and fallen under the illusion that he is,
in fact, a knight-errant of bygone days. His romantic dream is to right the wrongs in
the world, protect the defenseless, and act with courage and honor as he faces danger
and adversity.

In his adventures, Quixote does not
recognize ordinary people and situations for what they are. At various times, he
believes that windmills are giants, that herds of sheep are armies, and that a woman
traveling to Seville to meet her husband is a princess being held captive by "certain
enchanters," who are simply two priests who happen to be traveling on the same road. In
each instance, reality asserts itself, but Don Quixote explains it away by various means
and maintains his world of illusion.

His romantic dream is
finally destroyed, however, when he loses in his battle with the Knight of the White
Moon, an opponent who is really his friend Carrasco from Quixote's
village:

Being
mounted upon the swifter horse, the Knight of the White Moon met Don Quixote two-thirds
of the way and with such tremendous force that, without touching his opponent with his
lance . . . he brought both Rocinante [Quixote's horse] and his rider to the ground in
an exceedingly perilous
fall.

After this loss,
Quixote is honor-bound to give up his life as a knight-errant and return to his village.
Sancho Panza observes the effect this turn of events has on Don
Quixote:

He
saw his master surrender, heard him consent not to take up arms again for a year to come
as the light of his glorious exploits faded into
darkness.

Don Quixote is
carried home in a litter born by his friends, his body battered, his faithful horse too
injured to even stand, and his romantic dream finally destroyed by a reality he could
not overcome.

Once he is returned home, Don Quixote still
clings to his identity as a knight-errant until he awakens one morning, miraculously
restored to sanity:

readability="7">

I am no longer Don Quixote de la Mancha but
Alonso Quijano, whose mode of life won for him the name of "Good" . . . I am in my right
senses now . . . .

Don
Quixote is no more, and his great romantic dream will not live
again.

In The Crucible what are the outside factors responsible for John Proctor's death and how FAR are these factors responsible?I REALLY need help with...

I would do some research on the Salem Witch Trials to
prove this point. You might even look into some of the commentary sections of
The Crucible particularly in the
beginning.

Many researchers believe that what the girls
experienced was more of a reaction to a mold that had been in some of the rye bread. I
have attached an article for you to look through. It would position you to use science
or medicine as the last outside factor. I think it would compliment your religion
paragraph because the people were acting out of what they thought was going on, not
based on what really was going on.

Miller also confesses
that he altered the story for entertainment's sake but based in on true historical
facts. Proctor and Abigail in real life were 60 and 11. That their relationship was ever
as involved as Miller suggests is quite the stretch. But, John Proctor really was
hung.

In chapter seventeen what does atticus attempt to establish through heck tates's testimony.

In Chapter 17 of To Kill a Mockingbird,
Atticus Finch questions Mr. Heck Tate, Maycomb's law enforcement officer.  On the night of the
attack against Mayella Ewell, her father, Bob Ewell, went to Tate's office and "said get out to
his house quick, some nigger'd raped his girl."  Tate hurried to the scene of the supposed crime,
questioned the victim and her father, and observed details pertaining to the violent situation in
which Mayella seemed to have found herself. 

When Atticus requested
Heck Tate's testimony, he intended to prove two primary points, one of which was considerably
more significant than the other and should have resulted in the acquittal of Tom Robinson.  The
first, and least, of the two messages Atticus intended to send the jury was that Bob Ewell was,
in fact, not overly concerned with his daughter's health and well-being, since he did not attempt
to procure the services of a doctor for her.  This fact might suggest that Ewell was a poor
father figure and that he did not want to incriminate himself, which was a distinct
possibility.

The second point that Atticus attempted to make through
Heck Tate's questioning was that, considering his disability, Tom Robinson could not have harmed
Mayella Ewell in a way that would have resulted in her sustaining the injuries observed by Tate. 
Because Robinson's left arm had been injured when he was a child and, as a result, was useless,
Robinson could not have choked Mayella with both hand.  Furthermore, Robinson could not have
given Mayella a blackened right eye or bruised her "on her arms" or the right side of her face. 
Knowing this, the jury should have found it impossible to, in good conscience, convict Robinson
of the crimes of which he was accused.

Discuss what Whitman is saying about formal and informal learning in "When I Heard the Learn'd Astronomer."

This poem is a typically Romantic statement concerning education
and science. Key to note is the way that, after hearing the "learn'd astronomer" and his teaching
concerning the planets and stars, the speaker becomes "tired and sick." There is something about
the way in which the astronomer presents "the proofs, the figures" and "the charts, the diagrams"
which kills all mystery or ability to wonder and admire the beauty of creation. Scientifically
reducing such inexplainable wonders as the night sky to a series of "columns" which can be added,
divided and measured, robs the night sky of its mystery and glory. Thus it is that the speaker,
sickened by such a rationalistic attitude towards Nature, needs to go out himself and restore the
wonder of nature by simple appreciation of its beauty:

readability="13">

Till rising and gliding out, I wander'd off by
myself,

In the mystical moist night-air, and from time to
time,

Look'd up in perfect silence at the
stars.

Note the comparison between
this approach to the night sky and the one endorsed by the "learn'd astronomer." The speaker is
able to see the night sky as "mystical," obviously revelling in its mysteries and secrets. As
opposed to the speech with which the astronomer dissects the night sky, the speaker looks up in
"perfect silence" at the stars. Learning may be a great thing, Whitman seems to be saying, but
there is a danger of learning extracting all the mystery, pleasure, enjoyment and beauty of the
object that we are learning about if we are not too careful.

why can you use common factor to simplify?

The question given could be analysed in general. But this
attempt is only  to the limitted sense of solving problems related with rational fractions and
rational algebraic expressions.

If a  rational fraction in the form
p/q is given, we simplify it  to the lowest posissible integers in both numerator and
denominator.  The purpose is that it easy for graping and also it is easy to deal with further
calcalations in the simpler form.

Example 1: WE assume  a  given
fraction  like 21/77 is equal to 7*3/7*11.Here both numerator and denominators  have the common
factor 7. So we can divide both numerator and denominator by 7 and the result is
3/11.

 Example 2: The given expression, (x^2-1)/(x+1)  is equal
to (x-1)(x+1)/(x-1) The common factor is x-1. So we simplify the given expression to x+1 of
course x= not equal to zero.

Describe the main characters in the book Profiles in Courage.

Profiles in Courage is, of course, a
non-fiction book.  Its characters are real people from history.  In the book John F.
Kennedy (and the people who helped him write the book) profile 8 US Senators.  They are
the main characters of the book.

The space we are allowed
here does not allow me to go into a lot of detail on each man, but I would say that the
thing they have in common is that they all demonstrated what Kennedy thinks of as
political courage.  In other words, they all did at least one thing that they thought
was right even if it would cost them politically.  The book describes the thing or
things that each of the eight men did.

The eight men
are

• John Quincy
  Adams


• Thomas Hart
  Benton


• Sam Houston


• Lucius
  Lamar


• George Norris


• Edmund
  Ross


• Robert Taft


• Daniel
  Webster

How does Browning use imagery, figurative language, and sound qualities in "Porphyria's Lover"?

You have asked a very broad question concerning the entire
length of this rather complex poem. I am going to focus on one section of this poem that gives
such a rich and disturbing psychological insight into one man's desperate desire to possess
another human creature completely and utterly:

readability="14">

That moment she was mine, mine, fair,
Perfectly
pure and good: I found
A thing to do, and all her hair
In one long yellow
string I wound
Three times her little throat around,
And strangled her. No
pain felt she;
I am quite sure she felt no pain.
As a shut bud that holds a
bee,
I warily oped her lids: again
Laugh'd the blue eyes without a
stain

This quote is significant for a
number of reasons. Note the repetition of the word "mine" indicating the jealous possessiveness
of the narrator. His desire to possess forever someone who is "Perfectly pure and good" leads him
to strangle his lover with her own hair. Note how the metaphor transforms her golden hair into
"one long yellow string." We are also given an insight into the mind of the narrator, suggesting
that he may actually be an unreliable narrator, for he thinks that she experienced no pain, the
repetition of this statement perhaps suggesting internal doubt. He uses a simile to describe how
he opens her eyes, "as a shut bud that holds a bee," which again is another comparison to an act
of possession and ownership, which is what this complex poem explores through the poetic devices
employed.

I hope this helps give you an example of how poetic
devices are used in one section of this poem. Now go back and read the poem again, using my
response as a basis for analysis of the rest of the poem.

Give some examples of things that can be done to reduce the human impact on the environment, either as people or companies.

I'll give you a place to begin with a Top Five list of things to
do (or not do) that can reduce the footprint we leave on the
planet:

1)  Consume less - this is especially true in America, where
each person consumes many more resources than they should.  We can easily and safely use less
water, less gasoline, less electricity and we can buy less.  These are simple changes in our
daily habits that both save us money and benefit the
environment.

2)  Reduce our waste - We have become a disposable
society, where eating one fast food meal produces paper bags, napkins, wrappers, straws, cups,
etc., all for one meal.  Eating out once per week instead of three times, for example, reduces
such waste by 2/3.  Much of what we throw away can be recycled or
composted.

3)  Practice the saying "I don't need a bag for that". 
The tendency to put every single purchase, no matter how small, in a plastic bag is both
unnecessary and wasteful.  We don't have to be complicit by carrying them out of the
store.

4)  Companies can invest in energy conservation.  Sensors
that turn off lights when there is no movement in a room, public bathrooms that minimize water
usage, insulation and solar panels all can be green friendly ways a large company can both make a
difference and set an example.

5)  Cut down on packaging use -
Companies can request that the items they are sold not come in heavy duty plastic packaging,
that, while saving a little money in product loss/shoplifting, costs quite a bit and greatly
increases the amount of waste that comes with sales.  We used to get by with much less, and can
do so again.

To what extent is Eugene O'Neill's The Iceman Cometh autobiographical?

The setting of the play, Harry Hope's saloon, was taken from
O'Neill's own attendance of Jimmy-the-Priest's saloon and rooming house in the early 1910s.
O'Neill wrote the play in the last years of his life and The Iceman Cometh
is haunted by the same sense of death and despair that characterized the last part of
the playwright's life. To some critics, the play reflects the author's struggles with alcholism
and his disordered youth. It builds directly on O'Neill's encounters at Jimmy-the-Priest's and
the sense of hopelessness and being failed by the American Dream that these showed. The dive was
also the place where O'Neill attempted suicide in 1912.

In addition,
the character of Hickey appears to have much in common with O'Neill's older brother James, who
had proved a disappointment for Eugene. The third links below takes you to a comprehensive
New York Times article that reconstructs all the autobiographical elements
of the play. However, not all critics believe that the play can be read as an autobiography of
the author. See, for example, Eugene O'Neill's Last Plays: Separating Art from
Autobiography. By Doris Alexander. Athens: University of Georgia
Press.

What is the irony beind the title "Actors" of Chapter 6 of The Cold War: A New History by John Gaddis?

Gaddis uses the term "Actors" to describe the personalities
involved in the Cold War and its inevitable end. Only personalities with the ability to dramatize
the situation would be powerful enough to end the stalemate. Gaddis
writes:

"..real power
rested, during the final decade fo the Cold War, with leaders like John Paul II, whose mastery
of...courage, eloquence, imagination, determination and faith - allowed them to expose
disparities between what people believed and the system under which the Cold War had obliged them
to live....Accomplishing this required actors. Only their dramatizations could remove the mental
blinders, ...that had led so many people to conclude that the Cold War would last
indefinitely."

Gaddis also indicates
these personalities, Reagan, Thatcher, Pope John Paul II, and Gorbachev were successful due to
their "abilities to inspire audiences."

The irony is that both the
Pope and President Reagan had actually been actors. Pope John Paul II studied theater and poetry
at Jagiellonian University in 1938 until it was closed by the Nazis in 1938. Ronald Reagan had
been an actor prior to becoming governor of California, then President of the United States in
1980. Reagan made over 53 movies prior to his career in politics. Gaddis claims that it was this
dramatic ability of the personalities that helped people see the reality of the communist system
and its failings.

What is the solution of the equation 7^(3x-2)=17 in terms of logarithms?

7^(3x-2) = 17

First we will
apply the logarithm for both sides.

==> log 7^(3x-2)
= log 17.

Now we will use the logarithm properties to solve
for x.

We know that log a^b = b*log
a.

==> log 7^(3x-2) = (3x-2)*log
7.

Let us substitute into the
equation.

==> (3x-2)*log 7 = log
17.

Now we will divide by log
7.

==> (3x-2) = log 17 / log
7.

Now we will add 2 to both
sides.

==> 3x = (log 17/log 7)  +
2

Now we will divide by
3.

==> x = [(log 17/log 7) + 2 ] /
3

In Romeo and Juliet how does the Prologue of the play relate to Act 5 Scene 2?

Most of the prologue relates very well to Act V, scene
iii, but I will help you stretch the truth to fit scene
ii.

Scene ii is a scene between two friars. One is Friar
Lawrence who hired Friar John to get a message to Romeo. Friar John uses the scene to
confess to Lawrence that he could not get the message through to Romeo because of
the Black Plague... or the Black Death.

This is ironic
because the prologue refers to their "death-mark'd"
love.

Another point of interest would be the "star-crossed
lovers" because this would mean that the two of them are together quite unlucky. This
message not getting to Romeo is the most crucial detail of the fifth act because this
information would have saved two lives and they would have lived happily ever after.
However, because it doesn't get to him, the prophetic prologue is fulfilled.
 

What is the significance of dance in Praisesong for the Widow?

Dance is an essential part of Avey's African heritage.
Remember that Avey's great-aunt Cuney did not perform the Ring Shout dance properly. The
Ring Shout hails from a West African dance pattern, but Aunt Cuney was in a Christian
church. Marshall is showing how the West African tradition was "translated" as it moved
across to the Americas and changed through the years.

Avey
finds the Ring Shout insignificant as a child, and her lack of knowledge of her heritage
is a journey she must make both physically and spiritually. At the Big Drum dance
towards the end of the novel, Avey understands the different dances of the different
tribes that have been preserved, and dances her own version of the Carriacou Tramp.
Lebert Joseph says that she is an "Arada." She will now teach others about their
heritage in South Carolina.

If I have 10 different colored beads. In how many ways can I make a necklace?

This the permuations around a
ring.

Unlike the arrangements in a line the arrangements
around a ring , the starting and end points
coincide.

Therefore the order of the place does not
count.

Now, let there be n different (coloured)
beads.

So for a fixed place of the one particular bead  in
the necklace,  the number of arrangements of other n-1 beads = (n-1)!
ways.

If consider clockwise and anticlock wise as of no
consequence, then n different beaded necklace = could be in
(n-1)!/2.

Therefore 10 different coloured beaded necklace
could be in

(10-1)!  = 9! ways = 362880 ways (cw  and antcw
are considered different)

9!/2 = 181440 ways (cw and anti
cw are not consedred different.)

What are the new boiling point, and freezing point if: 25 g of NaCl is dissolved in 1.0 Kg of water?

When salt is dissolved in water the freezing point of water
drops below 0 degree Celsius which is the freezing point of pure water and the boiling point
rises above 100 degrees Celsius.

The exact change in the freezing
point is given by dTf = Kf*cm and the change in the boiling point is given by dTb = Kb*cm, where
Kf and Kb are constants for a liquid and cm is the the molality of
salt.

Here, we have 25 g of salt being dissolved in a kilogram of
water. The molecular mass of NaCl is 58.443 g/ mole. 25 g of salt is 0.4277 moles. The molality
of salt in water is 0.4277.

The constant Kf for water is 1.858 and
Kb is 0.521.

The change in the boiling point is 0.4277*0.521 = 0.222
degrees Celsius or the new boiling temperature is 100.22 degrees
Celsius.

The change in the freezing point is 0.4277*1.858 = 0.7947
degrees Celsius or the new freezing point is -0.7947 degrees Celsius.

What two or three personality characteristics are needed for me to be a successful accountant?

Think about the kind of work that accountants do and their role
within the work place. That should help you shape your answer. To me, one of the most important
personality characteristics for accountants would be having a good sense of
logic. If they think logically they, they will be able to approach
the accouting task in a manner that will best suit its successful and accurate completion. I see
having patience is part of this picture as well. With patience, all
of the calculations are checked; all of the data is collected and dealt with appropriately; no
short-cuts are taken that could affect the accuracy of the final product. Most accounts are
detail-oriented people who loved numbers and making it all work in
the end -- like a perfect puzzle with every piece in the right place. Accounts need to
be knowledgeable about current accounting practices within a company
as well as from a legal standpoint, but they all need to be flexible
thinkers who can approach and test a problem from a variety of angles or consider
multiple opinions, but then decide on the best course of action or method for the given
situation. As with any profession, there are lots of qualities that come together to make the
most successful people rise to the top of that profession.

The two
references below talk about personality traits and skills that are considered important in the

job.

Is Jane's marriage with Rochester a happy ending in Jane Eyre? If not, why?

Jane Eyre's marriage to Edward Rochester at the end of
Charlotte Bronte's novel, Jane Eyre, is a romantic one, certainly. 
For, earlier in the novel, Jane has so happily accepted Mr. Rochester's proposal of
marriage only to learn that he is already married.  Refusing to compromise her
principles, Jane leaves Mr. Rochester despite his
pleas:

"Jane,
do you mean to go one way in the world, and to let me go
another?"

"I do."

"....Oh,
Jane!  This is bitter. This--this is wicked.  It would not be wicked to love
me."

"It would to obey
you."

After Edward
Rochester's rebirth by fire, however, in which he is blinded only to really see, Jane
returns to Thornfield to love and cherish the man who now has paid for his sins.  For
Jane, the ending is, indeed, happy since she can love Mr. Rochester without compromising
her principles.  In addition, Jane's marriage to Mr. Rochester seems a reward for her
earlier denials of his proposal as well as that of St. John
Rivers.

In Macbeth, what quotes represent the hubris? (macbeth's excessive pride)

Hubris can be considered more than excessive pride in a person.
Hubris can also be too much ambition or even over confidence in a
character.

Macbeth is a prime example of a man filled with pride,
ambition and confidence. The reader sees this right from the start of the play. As soon as
Macbeth is named Thane of Cawdor,fulfilling one of the witches prophesies, he begins to
contemplate how to become king as the witches have suggested. The fact that he wants to be king,
and kills to become king, shows his ambition.

The second set of
prophesies allow the reader to examine Macbeth’s overconfidence. When the trees begin to march
against him as the witches warned, Macbeth still believes that he will live. He leaves the castle
with armor on his back and fights to keep his power. Even though the witches have tricked him
once, he still believes he is invincible as the witches told him. He fails to think about the
ways the witches have tricked him. This shows us that he is confident of his success, yet since
he is eventually killed by Macduff, we can see that his confidence was misplaced (an example of
hubris).

Hope this helps. Good luck!

What similarities do these two documents have?"Letter to John Adams" by Abigail Adams and "Declaration of Sentiments of the Seneca Falls Women's...

If one were drawing a historical continuum that linked
events, there could be an argument that one helps to lay the groundwork for the other. 
Examine this line from one of Adams' letters regarding the need to acknowledge women's
voices in the political and social discourse:

readability="11">

"...remember the ladies, and be more
generous and favorable to them than your ancestors. Do not put such unlimited power into
the hands of the Husbands. Remember all Men would be tyrants if they could. If
particular care and attention is not paid to the Ladies we are determined to foment a
Rebellion, and will not hold ourselves bound by any Laws in which we have no voice, or
Representation."

This
helps to bring out the idea that, at some level, the denial of voice will bring about
some level of profound change that could "foment a Rebellion."  Some might see the
Seneca Falls Convention as precisely this reality.  Stanton writes her Declaration as a
form of rebellion, demanding change to what she sees as the patriarchal system
representing a form of tyranny, men acting as "tyrants."  The rewriting of Jefferson's
document to speak for the voices of women is a deliberate attempt to bring about voice
and representation.  Adams' sentiments in her letters were recognized about 80 years
later.

What do we learn about life in Maycomb in the 1930s from the presentation of female characters in To Kill a Mockingbird?

In my opinion, chapter 24 helps draw many conclusions
about women and their roles in the 1930s.

First, we see
that women are expected to dress appropriately. Scout is criticized regularly by Aunt
Alexandra for her trousers and the description of Alexandra's physical appearance in
chapter 13 demonstrates her pride in Southern women's values for
appearances.

Second, we see that women are full of gossip.
Almost every situation that Scout notices in a woman besides Maudie includes great
gossip. Stephanie Crawford is portrayed as a great exaggerator. The Missionary Circle is
more about what is going on with the trial than the poor Mrunas they collect money
for.

Last, we see women as hypocrites who use their church
as a part of their lifestyle, but don't necessarily offer the grace, forgiveness and
kindness likely preached in their pulpits. Look at how some of the ladies discussed the
black community the day after a significantly unfair trial went down in
Maycomb:

Mrs.
Merriweather faced Mrs. Farrow: “Gertrude, I tell you there’s nothing more distracting
than a sulky darky. Their mouths go down to here. Just ruins your day to have one of ‘em
in the kitchen. You know what I said to my Sophy, Gertrude? I said, ’Sophy,‘ I said,
’you simply are not being a Christian today. Jesus Christ never went around grumbling
and complaining,‘ and you know, it did her good. She took her eyes off that floor and
said, ’Nome, Miz Merriweather, Jesus never went around grumblin‘.’ I tell you, Gertrude,
you never ought to let an opportunity go by to witness for the
Lord.”

Isn't that terrible?
The women must have had some positive traits, but I believe the reason Lee paints Scout
as a tomboy is because she herself is rebelling against the idea of being a Southern
Woman.

Verify the identity cos^2(a+b) + cos^2(a-b)= 1 + cos2a*cos2b

We'll write the formula for cosine of a
half-angle:

cos (x/2) = sqrt[(1 + cos
x)/2]

[cos (x/2)]^2 = [(1 + cos
x)/2]

We'll put (a+b) = x
so:

[cos(a+b)]^2 = [(1 + cos 2(a+b))/2]
(1)

[cos(a-b)]^2 = [(1 + cos 2(a-b))/2]
(2)

We'll add (1) + (2):

[(1 +
cos 2(a+b) + 1 + cos 2(a-b)/2] = 1 + cos 2a*cos 2b

2/2 +
[cos 2(a+b)]/2 +  [cos 2(a-b)]/2 = 1 + cos 2a*cos 2b

We'll
eliminate 1 both sides:

[cos 2(a+b)]/2 +  [cos 2(a-b)]/2 =
cos 2a*cos 2b

cos 2(a+b) +  cos 2(a-b) = 2cos 2a*cos
2b

cos 2(a+b) = 2[cos (a+b)]^2 -
1

cos 2(a-b) = 2[cos (a-b)]^2 -
1

cos 2a = 2 (cos a)^2 - 1

cos
2b = 2 (cos b)^2 - 1

2cos 2a*cos 2b = 2[2 (cos a)^2 - 1]*[2
(cos b)^2 - 1]

2cos 2a*cos 2b = 2{4(cos a)^2*(cos
b)^2-2[(cos a)^2+(cos b)^2] + 1}

[cos (a+b)]^2 = [cos
(a+b)][cos (a+b)] =
(cosa*cosb-sina*sinb)^2

(cosa*cosb-sina*sinb)^2 =
(cosa*cosb)^2 - 2cosa*cosb*sina*sinb +
(sina*sinb)^2

2(cosa*cosb-sina*sinb)^2 = 2(cosa*cosb)^2 -
4cosa*cosb*sina*sinb + 2(sina*sinb)^2

2[cos (a+b)]^2 - 1 =
2(cosa*cosb)^2 - 4cosa*cosb*sina*sinb + 2(sina*sinb)^2 - 1
(3)

2[cos (a-b)]^2 - 1 =2(cosa*cosb)^2 +
4cosa*cosb*sina*sinb + 2(sina*sinb)^2 - 1 (4)

We'll add (3)
+ (4):

2(cosa*cosb)^2 - 4cosa*cosb*sina*sinb +
2(sina*sinb)^2 - 1 +2(cosa*cosb)^2 + 4cosa*cosb*sina*sinb + 2(sina*sinb)^2 -
1

We'll eliminate like
terms:

 4(cosa*cosb)^2 + 4(sina*sinb)^2 - 2 = 2{4(cos
a)^2*(cos b)^2-2[(cos a)^2+(cos b)^2] + 1}

What are the major steps in developing effective marketing communications?

As a college senior and probably a business or marketing
major, this is a question that sounds like it is directed towards specific class or
textbook information, so keep that in mind as you read my answer, and tailor it to fit
what your instructor wants.

Step 1:  Set objectives for the
campaign.  Do you want to increase sales? Brand recognition?  Public good
will?

Step 2: Identify a market demographic for the
campaign - at which population will this campaign be aimed
at?

Step 3:  Plan to coordinate your marketing campaign
with other events and efforts, such as sales, holidays and other marketing efforts in
different media

Step 4:  Develop a specific marketing
plan.  Which media will you use?  How will your dollars be most cost effectively spent? 
When will the timing of the campaign take place?

Step 5:
Implement measures and strategies that can accurately track the success/results of your
campaign.

Step 6: Evaluate successes and flaws and make
adjustments to future plans.

Do you think Claudius' murder in Hamlet parallels the murder of Abel in the Bible? Explain your position.

The comparison of Claudius to Abel is an interesting one and I
encourage you to consider your own thoughts and feelings in addition to any you read
here.

Though the murder is similar in the fact that it is family
killing family and the motives could both be considered vengeful (or revenge), there is such an
enormous difference between Claudius and Abel (as in, their characters) and the circumstances
surrounding the murders, that I personally would not consider the two stories to be
similar.

Abel was killed because Cain was jealous of his brother and
the sacrifice he was bringing to God. At the core, Abel was the better brother in the eyes of
God, and for this Cain was angry. In this story in Genesis, most consider Abel to be a victim and
Cain to be an antagonist.

Hamlet is angry at Claudius for an
entirely different reason. Claudius killed Hamlet's father (and then proceeded to arrange
Hamlet's death, which resulted in the deaths of many more). In this cause, Hamlet is
the victim and Claudius is the antagonist. Hamlet killing Claudius seems far more
justified than Cain killing Abel, so I would not personally consider these examples to be
parallel.

Elucidate the following statement about productivity.productivity is an important tool for managers as it helps to track progress toward the more...

Productivity is not just a tool of management. It is more of an
important purpose or objective of management. As productivity is an important objective of
management measuring and monitoring productivity is definitely an important tool for
managers.

However there is a need to be clear about the means and
objectives. The statement made in the question:

readability="6">

... productivity is an important tool for managers as it
helps to track progress toward the more efficient use of resources
...

reverses the correct sequence.
Productivity is not important because it helps to track progress towards efficient use. Rather
tracking of efficient use is important as it helps to improve
productivity.

While on the subject, it will be appropriate to
differentiate between efficiency and productivity. While efficiency concentrates on reducing
input resources employed, productivity concentrates on increasing the output. We can improve
labour productivity by increasing automation and capital resources. Such and increase in labour
productivity cannot be attributed to increase in labour efficiency. Thus, I disagree with the
statement made in the previous answer posted that productivity is a measure of
efficiency.

What does "systematic violence" mean?

Animals fight and their instinctive will to survive at all
costs ensures survival of the fittest. It is imperative in ensuring the continuation of
a species. Their lack of compassion and sometimes brutal treatment of each other is not
due to anger or irrational beliefs. Mankind is supposed to be unique and does not have
this requirement to fight to the death in order to survive. Violence, therefore, is a
social construct.  It is destructive in nature and violent behavior is socially
unacceptable. It involves physical exertion and can be an individual or a group against
an object, another person, a group or members of a group. It always has consequences
whether they are physical or emotional.

In Social Sciences,
systematic violence refers to a type of collective action, sometimes prompted by culture
or religion and sometimes by prejudice. Hate crimes, brought on by intolerance, have
marginalized minorities who have a different sexual orientation, religion, ethnicity,
race and so on, from those around them. These groups have been targeted and even driven
out of neighborhoods. Xenophobic violence is one such example when large groups of
people "systematically" drive others out of their community through violent and cruel
treatment.

There are also cultural differences which often
contribute to their own system of systematic violence. What some cultures allow other
cultures find oppressive, demeaning and totally unacceptable, resulting in heinous
crimes such as murder. Honor killings would be one such example of cultural violence
which in the twenty first century certainly falls within the scope of systematic
violence. Within certain communities, honor killings, usually against women, are
considered to be justified and there are therefore no repercussions for the
perpetrators. The violence is planned and carried out in terms of an apparent higher
authority beyond the law, and no consideration is given to the establishment of proof of
wrongdoing or the ends of justice. Perception of having wronged her family is enough
cause for violence, which sometimes ends in
death. 

Systematic violence has existed for hundreds of
years as people have been oppressed and treated violently by the very people and systems
designed to protect them, including governments, making some systematic violence
political. The Mafia is another example of systematic violence. Differences,
misunderstandings and unhealthy competition have ruined many lives through systematic
violence. 

Taoists disdain the social world. Explain.

The basic belief systems of Taoism are ones predicated
upon individual embraces of understanding and enlightenment.  I am not sure if "disdain"
is too strong a word, but Taoists believe that this is a process where individuals find
their own path to follow within the Taoist faith.  This is not necessarily seen as a
communal process, whereby one has to follow a group or social sect of being.  Rather,
the Taoist community is defined by the individuals within a particular group.  The "tao"
itself is something that individuals have to find, the "way" is something that must be
found internally.  A Taoist society can be established, and there are social setting
where Taoism is evident.  Yet, I think that that following of "the tao" is not something
that can be done as a group or as a collective entity.  The ability to find one's own
path is compromised to an extent when in a group.  It might be to this extent that
Taoists perfer the spiritual explanation to take place on an individual basis and not
one that is social, in nature.

What are two convex functions, f and g, such that the composition f(g(x)) is not convex?

A function f(x) is convex if f''(x) >= 0 for all
x.

Now we have to find two functions f(x) and g(x) such that they
are convex but f(g(x)) is not convex.

If we take f(x) =
-x

f'(x) = -1

f''(x) = 0 which is
always >=0.

Therefore f(x) = -x is
convex.

Take g(x) = x^2

g'(x) =
2x

g''(x) = 2 which is always
>=0

Therefore g(x) = x^2 is
convex.

Now f(g(x) = f(x^2) =
-x^2

f'(g(x)) = -2x

f''(g(x)) = -2
which is not >=0

Therefore f(g(x)) is not
convex.

One example of f(x) and g(x) being convex but
f(g(x)) not being convex is f(x) = -x and g(x) = x^2.

If 3 and 5 are roots of the quadratic function f(x) , find f(2)

If 3 and 5 are roots of the quadratic function f(x) , find 
f(2)

First we need to determine the function
f(x):

We know that:

if x1 and x2 are
roots for the function, then ( x-x1) and ( x-x2) are factors of the
function:

Then we conclude that ( x-3) and (x -5) are factors of
f(x):

==> f(x) = (x-3) (
x-5)

Let us expand the
brackets:

==> f( x) = x^2 - 3x - 5x +
15

==> f(x) = x^2 - 8x + 15

Now
that we found f(x) we will calculate f(2) by substituting with x=
2:

==> f(2) = 2^2 - 8*2 +
15

==> f(2) = 4 - 16 +
15

==> f(2) =
3

Should Lincoln's position in handling the secession crisis be judged favorably or unfavorably?

I would argue that you have to judge Lincoln's position
favorably.  I do not think that Lincoln could have done any better than he
did.

When Lincoln was elected, the South already distrusted him
completely.  Even so, Lincoln tried to allay their suspicions.  He gave a number of conciliatory
statements, saying, for example, that he would not try to end slavery in the South.  There is not
much more that he could have done in that regard.

The other choice
he had to make was whether to just let the South secede.  You can say he should have just let
them go rather than having a way, but that is unrealistic.  I cannot imagine any president
thinking that it would be a good idea to just let half of the country leave and become a
potentially hostile power right next door to the United States.

Why did Tolken write The Hobbit? Source of info?

The Hobbit originally came about when
Tolkien was a professor at Oxford in the 1930s. One day when Tolkien was marking student papers
and came across a blank page, he unaccountably scribbled the famous opening line of the novel:
"In a hole in the ground there lived a hobbit." Much later in 1955 in a letter to his former
student, W.H. Auden, Tolkien writes: "On a blank leaf I scrawled: 'In a hole in the ground there
lived a hobbit.' I did not and do not know why.'" (qtd. in History of the
Hobbit). The idea of the character intrigued him, trying to decide who and what a
Hobbit is exactly. He occasionally used his growing story to amuse his children at home, even
incorporating some of the adventures into 'Father Christmas' letters he wrote for them. Two years
later, the manuscript for The Hobbit was complete.

In "Dr. Heidegger's Experiment," what does he tell them about the rose?

Dr. Heidegger presents the rose to his guests at the
beginning of his proposed "experiment," the nature of which remains a mystery to his
friends who are just about to be experimented upon. As Dr. Heidegger takes out the
remains of a rose from his folio, he tells his guests its
origin:

"This
rose," said Dr. Heidegger, with a sigh, "this same withered and crumbling flower,
blossomed five and fifty years ago. It was given me by Sylvia Ward, whose portrait hangs
yonder; and I mean tot wear it in my bosom at our wedding. Five and fifty years it has
been treasured between the leaves of this old volume. Now, would you deem it possible
that this rose of half a century could ever bloom
again?"

Thus we are told that
the rose relates to Dr. Heidegger's only love of long ago, who, we have already been
told, was killed in a terrible accident when Sylvia Ward took a medicine prescribed to
her by her fiancé. Dr. Heidegger uses it as a demonstration of the power of the Water of
Youth, but also he uses it at the end to highlight the message of the story about the
value of old age.

Please tell me the proofreading mark for "Write out in full."

Proofreading marks are very specific and well defined.
There are twenty-six well known proofreading marks. The mark indicating that something
in a text needs to be written out in full is identified as the "Spell out an
abbreviation or a number" mark. It may be confused with the "Reconsider word choice"
mark or with the "Check the spelling of a word" mark. You can see that though these may
seem similar, each has a very specific and well defined
function.

To make the "Spell out an abbreviation or a
number" mark, or symbol, which may also sometimes be called the "Write out in full"
mark, or symbol, you simply draw a distinct and neat oval around the abbreviation or
number in question that needs to be written out. The oval will be widest from side to
side regardless of the size of the abbreviation or
number.

This symbol may be confusing because it is
identical to the "Abbreviate a word" symbol: both symbols are an oval. What
differentiates the one from the other is that the one oval encloses an abbreviation or
number that must be written out in full, while the other oval encloses a fully written
word (or number) that must be abbreviated (or written as a
numeral).

find the inverse formula for the function f(x)= 3x-7

To determine the inverse function means to determine x with
respect to y, from the given expression of f(x).

We'll note f(x) = y
and we'll re-write the equation:

y = 3x -
7

We'll use the symmetryc property:

3x
- 7 = y

We'll isolate 3x to the left side. For this reason, we'''
add 7 both sides:

3x = y + 7

Now, we'll
divide by 3 both sides to get x

x =
(y+7)/3

The inverse function is f(y) =
(y+7)/3

By definition, we'll write the inverse function
as:

f^-1(x) =
(x+7)/3

f^-1(x) = x/3 +

How was ethnicity of Hutu and Tutsi socially constructed by the Belgians?

In 1916 Belgians took control over the area as a colony.
 Prior to this the Hutu and Tutsi were were both living in two kingdoms in the
region, Ruanda and Urundi, with both being ruled by the same king. While they identified
as different groups, intermarriage was common and there was little animosity between the
groups.  When the Belgians colonized the two kingdoms they chose the Tutsi, who
comprised about 14% of the population, to be the ruling class.  They were chosen both
because this gave the Belgians a proxy to act for them in the region, and because the
Belgians felt that the Tutsi were biologically superior to the
Hutu.

It was therefore the Belgians who socially
constructed the ethnicity of these two groups into what they became post-colonization.
The labels imposed on the Tutsi for being superior caused the Hutu (who always made up
the majority of the population in both the precolonial kingdoms and
the Belgian colony)to become second class citizens, which they then rebelled against.
This rebellion is what led to
the Rwandan genocide.

How would you describe the style within which "An Occurrence at Owl Bridge Creek" was written?

This is undoubtedly a tense, suspenseful tale that keeps us on
the edge of our seats until the final, rather shocking ending. Key to the style that Ambrose
Bierce employs in this tale is his use of point of view and also the way that he presents the
major events but in a non-chronological fashion.

At various stages
in the story, the narrator switches between different points of view to report the action,
varying between omniscient point of view, an objective point of view (in which the narrator
reports without comment) and lastly a third-person limited point of view. For example, Bierce
uses the third-person-limited point of view to describe Farquhar's desperate flight of
imagination:

By
nightfall he was fatigued, footsore, famishing. The thought of his wife and children urged him
on. At last he found a road which led him in what he knew to be the right
direction.

This allows Bierce's
narrator to maintain a realistic stance--even as his mind flees reality. You might also want to
think about the way that the story is told in non-chronological order. Clearly this stylistic
device reinforces the intense pressure and psychological escape that we are witnessing in the few
seconds before Farquhar dies, but if the events were narrated in chronological order, the reader
might feel more sympathy for Farquhar before his hanging, diminishing the dramatic contrast
between Parts I and III of the story.

Thus, if you want to comment
on the style of this classic tale, considering the varying of the points of view and the
non-chronological way that the story is related should give you a variety of comments to make.
Good luck!

Why is it essential for the Party to rid the language of synonyms and antonyms in 1984?

The Party would claim that the purpose for this is to stop the
use of words that are unnecessary. In fact, it makes things clearer, less ambiguous, and simpler
for the people. Isn't that thoughtful of the Party? The people even believe this about the
principles of Newspeak.

However, in truth, what this actually does
to a society is dumb them down. When vocabulary has limits placed on it, the ability to have an
awareness of the world decreases. Words are the colors to thought and intellect. Much like
textures and colors, words can meet quite near the same thing, but not exactly something
else.

For example, you can't just become
untremendous in your job. That negation of a positive word feels like a
fruitless meaning. You could be told you are doing mediocre, or you are
slacking. Each of these provide a specificity for why you are no longer
tremendous. But this is the Party's true aim, to get people to stop thinking because it is easier
to control a people who do not think.

What is the lowest possible temperature?

Scientists believe that the lowest possible temperature
that can be achieved is -273.15 degrees centigrade. This temperature, which is also
called absolute zero, has been established on the basis of observation of relationship
between temperature and pressure of a gas. When a given mass of gas contained in a fixed
volume, its pressure decreases in direct proportion to its temperature. This phenomenon
means that at the absolute zero temperature of all gases mus fall down to
zero.

In the kelvin unit of measuring temperature, the
absolute zero is taken is zero temperature. It is impossible to reach 0 degrees kelvin
temperature. The lowest temperature so far reached in laboratories is of the order of
0.00001 degree kelvin.

Prove that the function arctanx is concave over the interval [0,infinite].

In order to prove that f(x) is concave, we'll have to
calculate the second derivative of the function.

If the
second derivative is negative, then the graph of f(x) is
concave.

For the beginning, we'll calculate the first
derivative of
f(x):

f'(x)=1/(1+x^2)

Now,
we'll calculate f"(x) of the expression arctan x, or we'll calculate the first
derivative of f'(x).

f"(x) =
[f'(x)]'

Since f'(x) is a ratio, we'll apply the quotient
rule:

f"(x) =
[1'*(1+x^2)-1*(1+x^2)']/(1+x^2)^2

We'll put 1' = 0 and
we'll remove the brackets:

f"(x)=
-2x/(1+x^2)^2

Because of the fact that denominator is
always positive, then the numerator will influence the
ratio.

Since numerator is negative over the interval
[0,infinite), f"(x)<0.

So, the function arctan x is
concave over the interval [0,infinite).

"How many ages hence/Shall this be our lofty scene be acted over/In statres unborn and accents yet unknown."What does this quote mean in Julius...

These lines are spoken by Cassius after he and the other
conspirators have assassinated Julius Caesar.  Since there is a panic that follows this
act, Brutus, as leader of the conspirators, reassures them, "Ambition's debt is paid"
(3.1.91).  In order to mark themselves as the men who have given Rome "Peace, freedom,
and liberty" (3.1.89), Brutus instructs the men to "bathe" their hands in Caesar's blood
and "besmear" their swords before they walk to the market place. Then, in the thrill of
this moment of glory for them, Cassius encourages the others to follow Brutus's
directions.  His words indicate that he believes that they will be praised by the Romans
for relieving them of a tyrant, and in recognition of the greatness of the
conspirators, their act of freeing Rome from the rule of Julius Caesar will be reenacted
throughout the world.  Of course, Cassius's declaration is ironic as Antony turns the
Romans against the conspirators and they riot, causing a civil war that is far worse
than the rule of Julius Caesar.

Determine the equation of the circle whose circumference is 14*pi and the center is (3,-2).

Given the circumference of a circle is 14pi and the center
is at the point (3,-2).

We need to determine the equation
of the circle.

First, we need to write into the standard
form of the circle:

(x-a)^2 + ( y-b)^2 =r^2 where (a,b) is
the center and r is the radius.

==> (x-3)^2 + (
y+2)^2 = r^2.

Now we need to find the radius of the
circle.

Given the circumference C =
14pi.

==> 2*r*pi =
14pi

==? r= 14pi/ 2pi = 7

Then

In Chapter 15 of To Kill a Mockingbird, discuss why the men in the cars show up at the jailhouse so late?

The group of men from Old Sarum (mostly Cunningham family
members, apparently) showed up at the jail with the intent of lynching Tom Robinson. Atticus had
been warned by some townspeople earlier that Tom's stay in the local jail may not be safe, and
there is also mention of the Ku Klux Klan afterward. It is safe to assume that the men were
planning to take Tom from the jail by force while Sheriff Heck Tate was out "on a snipe
hunt"--investigating a bogus call that sent him "deep in the woods" deliberately meant to keep
him away from the jail. As in many scenes in To Kill a Mockingbird, the
darkness of the night is meant to hide the activities of its characters (Boo prowling around at
night, Jem paying night visits to the Radley house). The lynch mob probably thought it would be
safer to take Tom and hang him in the shadows of the night in order to better protect their own
identities .

Does anyone have the theme to the poem?

“Eating Poetry” is unique, however, because it emphasizes
the pleasure and joy of learning. Indeed, the poem is an intellectual romp, just like
the dogs coming up the stairs (line 9) to devour more poems. Poetic allusion in the poem
may be seen in the phrase “eyeballs roll,” an overstatement to indicate the throes of
passion which is used by Pope in “Eloisa to Abelard” (line 323). In addition, the phrase
“bookish dark” (line 18) recalls Frost’s “pillared dark” in the poem “Come In.” In
Frost, the pillared dark is like an invitation to come in and change the speaker’s life.
Here Strand uses the phrase similarly, for the “bookish dark” has effected such a change
in the ebullient speaker.

How did African Americans survive during the Great Depression.

The Great Depression worsened the lives of African Americans,
making segregation, disfranchisement and privation of civil rights a recurrent experience in
their existences. Hoover's Administration did little to protect African Americans from white
violence and to improve their condition. Many sought to leave the South and move North, but even
there they had to face prevailing racist views. The migration to the North made African Americans
less tied to the land and agriculture in favor of menial jobs in Northern
factories.

The early 1930s were also marked by the Scottsboro Trials
where nine African Americans were unjustly accused of having raped two white women. In this
political context, African Americans turned to their traditional religious institutions, but also
to secular political organizations like the Communist Party that fought for their rights.
Historians are still debating the extent to which the CPUSA really fought for the rights of
African Americans or used equality to attract more members. An interesting study of the
relationship between the CPUSA and African Americans is New Negro, Old Left
(1999) by William Maxwell who revises the standard thesis of Communist manipulation
put forth by Harold Cruse in his classic book The Crisis of the Negro
Intellectual (1967).

With the election of F. D. Roosevelt
to the presidency, African Americans became an important part of the New Deal coalition,
switching to the Democratic Party. The WPA and other New Deal relief agencies helped African
Americans in their economic struggles. In addition, Roosevelt appointed several African American
advisers. An important symbolic event was the First Lady's invitation to African American
contralto Marian Anderson to sing at the Lincoln Memorial on 1939 Easter Sunday after the
Daughters of the American Revolution had prohibited her to sing in Washington's Constitution
Hall. Yet, although this gave the impression that New Dealers were committed to civil rights, the
administration never suggested laws against lynchings or to abolish the poll tax. The New Deal
thus has a mixed record as far as African Americans are concerned.

What is performance evaluation?

As it states in its title, "a performance evaluation" is a
tool used to assess how an individual is performing in a given capacity.  It is used for
a variety of reasons.  In some organizations, it can be strongly linked to upward
professional and economic mobility.  It can also be used as a tool for professional
growth and advancement.  Some performance evaluations are geared towards making an
individual more proficient in their given field.  This can be done by being able to
identify specific goals and objectives that must be worked on by the professional.  I
think that a performance evaluation can be used in this domain in order to make an
individual able to contribute more to their given vocation.  In different realms,
performance evaluations can be used to not only reflect an individual in a particular
organization, but also an individual as a professional, as well.

What is the rising action in the play "Trifles" by Susan Glaspell?

The plot of any piece of literature consists of the
exposition, rising action, climax, falling action, and denouement. The exposition offers
background information and an introduction to the characters and conflicts. The rising
action is the complication of the events, where the conflicts become more involved. The
climax is the most intense moment of the story, and the falling action is what happens
after the climax. Denouement ties up any loose ends and clarifies any
events.

The climax of this story is when the two women find
the dead bird and realize that John Wright had broken its neck, taking away from Minnie
the only joy she had in her sad life. The exposition starts at the beginning of the
play, giving us the background of how John Wright's body was discovered and how they
found Minnie sitting in her rocking chair. The rising action begins when the men go to
look for "important" clues upstairs, leaving the two women in the
kitchen.

How does George Orwell present conflict in Animal Farm?

Even in the animal world of George Orwell, conflict is a
constant presence. The battle for control between Snowball and Napoleon continues until Snowball
leaves the farm. There is conflict between the humans, culminating in the two major battles--both
won by the animals. The animals are angered when they are given forged banknotes as payment for
the timber. Four pigs were executed after they were forced to admit that they were agents of
Snowball. Several hens rebelled about having to give up their eggs. By this time, Napoleon had
secured his strong position as head of the farm, and most of the animals' voices were silenced.
Many questioned the apparent changes to the commandments, and several were horrified at the cruel
retirement awarded to Boxer. They wondered about the pigs' growing human qualities--sleeping in
beds, dressing in clothes, drinking and walking upright--but they mostly remained silent as the
Animal Farm eventually evolved back to its origins of Manor Farm.

What are some patterns that occur in "Lamb to the Slaughter" by Roald Dahl?

I am not entirely sure what you mean by "patterns," but
certainly one re-occurring aspect of this tale is the use of ironic twists that occur
throughout the tale and keep us guessing and laughing with black humour until the very
end.

The first element of irony you will want to note and
which can then be followed through in the tale is the actual title itself. This title is
a deliberate allusion to the innocent, white lamb that was slaughtered. Clearly, Mary
Maloney can be seen as this lamb at first, and yet, with situational irony, we see that
it is she who kills her poor unsuspecting husband rather than the opposite. This irony
is furthered as she, completely surprisingly for an unsuspecting housewife, displays
massive criminal intelligence in organising an alibi for herself and then getting the
police officers to ensure that the murder weapon will never be found, guaranteeing her
freedom:

One
of them belched.

"Personally, i think it's right here on
the premises."

"Probably right under our very noses. What
you think, Jack?"

And in the other room, Mary Maloney began
to giggle.

Thus focussing on
the various patterns of irony as they run through the story reveal the grimly humorous
nature of this excellent short story.

Explain the meaning of "A Time Past."

In my opinion, this poem means that, although time passes,
we keep what is important in our hearts.  These things that we retain are much more
important than the physical things that we lose.

We can see
this in how the physical things in this poem have been lost.  Specifically, the wooden
steps are no longer there.  They are off somewhere, waiting to be
burned.

Even though the steps are no longer there, the
memories that are associated with them are there.  They linger in the speaker's heart
and they make her happy even after time passes and physical things are
gone.

In Chapter 58 of Great Expectations, what does Pumblechook publicly instruct Pip to tell Joe?

In Chapter 58, Pumblechook is trying to take credit for
Pip's previous good fortune -- for the fact that Pip got to go off and be educated. 
Because of this, he tells Pip to tell Joe that he (Pip) has seen the man who had helped
him (Pip) out.  He is supposed to imply to Joe that Pumblechook is the one who is
responsible for Pip's "great expectations."  You can see this in the following quote
spoken by Pumblechook to Pip:

readability="14">

"I will tell you, young man, what to say to
Joseph. Says you, "Joseph, I have this day seen my earliest benefactor and the founder
of my fortun's. I will name no names, Joseph, but so they are pleased to call him up
town, and I have seen that
man."

Pip refuses to do
this.  When that happens, Pumblechook starts to make him look bad in front of all the
people.  He makes it look like he is the benefactor and that Pip is an ungrateful
person.

What was the Townsend Plan?

The Townsend Plan was something that was suggested by a doctor
from California named Francis Townsend. He proposed it because he did not believe that the New
Deal was doing enough to help the elderly poor.

Under Townsend's
plan, all retired Americans would receive payments from the government. Townsend proposed that
everyone over 60 years old who retired would be paid $200 per month. Please realize that this was
a huge sum in those days. The only stipulation would have been that the recipients would be
required to spend the entire $200 each month. By doing so, they would be creating a great deal of
demand for goods and services. This would help the elderly themselves and would also get the
economy going as businesses rushed to provide the seniors with the products they
wanted.

The publicity surrounding Townsend's plan helped to push FDR
towards creating Social Security.

Theme of cruelty in Chapter 22. Discuss the idea please.

Chapter 22 is the climatic confrontation of Amir and
Assef.  Amir has come to this place on a mission to get Sohrab, but it won't be that
simple.  He first must confront the physical and psychological cruelty of Assef.  The
psychological cruelty comes in many small and large
ways:

1.  He must enter the room alone, and he is
surrounded by armed men who pat him down and are very
intimidating.

2.  He must sit and silence, observing a
Talib man who is had blood from the morning execution still on his clothing and who
speaks positively about the idea of public executions.

3. 
The Talib and the others pull off his fake beard, exposing him to be an American, which
they ridicule.

4.  The men in the room tell terrifying and
gruesome stories about the Hazara massacre after the Taliban take
over.

5.  They taunt Amir and tell him he should be
frightened right now.

6.  They bring Sohrab in and his
resemblance to his father is so striking that it almost takes Amir's breath away, but
this only heightens Amir's need for this rescue to be successful.  Failure is
frightening.

7.  Amir's long-lost enemy/bully, Assef, comes
into the room and recognizes Amir from their
childhood.

After Amir processes all of this psychological
torture, he then must endure the physical torture of a the beating he receives from
Assef.  Assef uses brass knuckles to deliver the terrible blows as Amir swallows broken
teeth, gets hurled against the wall, hasribs and facial bones broken by the brutality of
Assef.  The final straw for Assef is Amir's breaking into laughter over it all.  This is
not joyful laughter, but the laughter that comes when a person is actually feeling full
out terror for his life.  The cruel beating ends when Sohrab, so much his father's
son, uses his slingshot to take out Assef's eye -- exactly like Hassan had threatened to
do it when they were all youths.

The mix of psychological
and physical cruelty in this chapter creates an immense amount of pathos in the reader,
and we are as relieved as Amir when the chapter(scene) finally
ends. 

In "Roman Fever," why are Mrs. Slade's black brows drawn together "as though references to the moon were out-of-place and even unwelcome"?

There is a sense in which the moon is symbolic in this excellent
short story. For these two middle-aged women who are now widows, and are only able to live the
joys of youth vicariously through their daughters, it appears that the moon is a symbol of what
they have lost or passed through their age, and perhaps it is also a symbol of the way in which
Alida Slade tricked her friend into meeting her husband at night in the
Forum.

Note the way in which Alida Slade says, somewhat
disparagingly:

readability="6">

"Moonlight--moonlight! What a part it still plays. Do you
suppose they're as sentimental as we
were?"

Alida here refers to their
daughters and the way that moonlight is associated with romance and love. Thus the moon seems to
operate as a symbol that recalls their own youth and the role that romance and passion played in
their lives, and simultaneously the way that those days have passed for them now and can never be
reclaimed. This is why Alida Slade greets references to the moon with such a
response.

How does the sniper specifically solve the threat to his life?Question on Resolution

Specifically, the sniper in this story solves the threat
to his life through trickery.  The main threat to his life (after he has killed the man
in the turret) is from the enemy sniper.  He tricks the enemy sniper into believing that
he is dead.

He does this by putting his cap up on his rifle
and sticking it above the parapet.  When the enemy shoots it, he lets the rifle fall to
the street after letting the enemy see it dangling in his (seemingly dead) hand for a
bit.  When the enemy gets up (thinking the sniper is dead) the sniper shoots him with a
pistol.

Given that a+b = pi/2, prove that sin 2a+sin 2b=2cos(a-b)?

We'll transform the sum sin 2a+sin 2b into a
product:

sin 2a+sin 2b = 2sin [(2a+2b)/2]*cos
[(2a-2b)/2]

We'll factorize by 2 inside the
brackets:

sin 2a+sin 2b = 2sin [2(a+b)/2]*cos
[2(a-b)/2]

We'll simplify and we'll
get:

sin 2a+sin 2b = 2sin [(a+b)]*cos
[(a-b)]

But, from enunciation, a+b =
pi/2.

sin 2a+sin 2b = 2sin [(pi/2)]*cos
[(a-b)]

But sin pi/2 = 1

sin
2a+sin 2b = 2cos [(a-b)] q.e.d.

Why does Congress have subcommittees?AMERICAN GOVERNMENT 2

Congress has subcommittees for the same reason that it has
the larger committees.  I would say that there are two main
reasons.

First, it is useful to have subcommittees to allow
members of Congress to have influence over policy areas in which they have some
expertise.  It makes sense to have the people who know and care the most about some area
of policy be the ones who have the first shot at marking up bills and suggesting what
sorts of policies should be implemented.

Second, it is much
more efficient to have small groups work on proposed laws.  Imagine if every bill that
came before Congress had to be marked up on the floor.  It would be chaos because of the
numbers of people involved.  It would also make it very hard to get anything done
because there are so many bill proposed.  So having various committees and subcommittees
allows Congress to take care of more business more quickly.

After his encounter in the forest with Goody Cloyse, Goodman Brown tries to resist the devil's temptations by raising what issue?

In Nathaniel Hawthorne's story, "Young Goodman Brown,"
Brown discovers, to his horror, that the woman who taught him his catechism (Goody
Cloyse) is in league with the Devil, and he is horrified and
disheartened.

At this point, Brown sits down on a tree's
stump along the forest's path and refuses to proceed with the Devil any farther on their
journey.

The argument Brown presents to the Devil is that
even if Goody Cloyse had been responsible for teaching him about his faith while he has
all along believed her to be a good woman of God, what would possess him now to abandon
his wife, Faith, to follow the old woman instead?

If
Brown's speech here is figurative, he may be arguing with the Devil or himself, but
"Faith" may not refer to his spouse, but to his belief in God, and his determination is
not to stray from the "straight and narrow" path that leads to heaven. His argument
would sound a great deal like a parent's admonishment, "If Johnny decides to jump off of
a bridge, does that mean you will do it too?" He is saying,
"no."

Brown may mean that just because a woman he believed
had a strong faith fails, and chooses to "traffic" with the Devil, it does not mean that
he will turn his back on what he believes simply because the old
woman's faith was not strong enough.

The irony is that at
the end, Brown does almost the same thing. He may not intentionally join the Devil, but
he does turn his back on Faith and his religion, and in this manner, the Devil may be
thought to have "won" anyway.

How do these early theories of African history still affect western views of the history of black Africa and its peoples? ...

Much of what ends up coming out of the video clips is the
notion of how imperialism and colonialism impacted the narrative of African History. 
The difference in perception between both Western History and African History is
revealed in the oral tradition of historical development.  The fact is that imperialism
had a detrimental impact on two levels.  The first is that those who were the torch
bearers of this history were wiped out due to old age, enslavement, breaking of
villages, so that this history never went on a formal record.  In addition to this,
enslavement and the displacement of slaves from Africa made its historical tradition
impossible to pass down.  In the end, Western thought for a long time believed that
there was no history to Africa because it was never "on record."  Consciously or not,
Western thought did much to destroy this historical record through its actions that
served to silence and served to negate African History.  I think that there is a general
consensus that suggests this is not the case today.  The opening of the first video
where an Oxford History Professor would claim that there is "no history to Africa" is
not something that would be suggested by even the most novice of professionals today. 
There is a general understanding and acceptance that Africa's history became profoundly
skewed and distorted by the West and that there was history even before the West entered
into African historical consciousness.  We now know that we can obtain a great deal of
historical detail on Africa, removing its label of the "dark continent," through a
simple search that integrates the role of the West in the process of African historical
identity.

What is a double blind study?

A double blind experiment is one in which a specific
technique is used to make sure that the researcher does not influence the subject to
pick one choice or another.

Take for example a taste test
for which soft drink people prefer.  In a double blind test,
neither the researcher nor the person drinking would know
which soda is which.  That way, the researcher would not be able to give hints (either
on purpose or accidentally) as to which one the person drinking should choose.  This is
why the study is "double" blind -- both the researcher and the test subject are "blind"
because neither of them knows which choice is
which.

Perhaps a more scientific example would be in a test
for a medicine.  If a doctor is giving some patients a real medicine and some a placebo,
the doctor must not know which is which.  If they did know, they might act differently
when doing it and that would tip off the patient as to which thing they were getting. 
This would spoil the test.

Verify if the lines are intercepting? x+y = 20 3x - 2y = 6

The lines x+y = 20 and 3x-2y= 6 must inersect as their
slopes are obviously looking different.

Slope of x+y = 20 
or y = 20-x (which is in y = mx+c , m is slope ) is
-1.

Slope of  of 3x-2y = 6 or -2y = -3x+6 ,  or y
=(3/2)x- 6/2 , is
3/2.

Intersection of the lines are the solution of the
equations:

x+y =
20..............(1)

3x-2y =
6..................(2)

Add 2*eq(1) and eq(2 ) . Then y gets
eliminated:

2x+3x = 2*20+6 =
46

5x=46

x = 46/5=
9.2.

Eq(3)*3 - Eq(2) eliminates
x:

3y- (-2y) = 3*20-6 = 56

5y
= 56

y = 54/5 = 10.4

Therefore
(x,y) = (9.2 , 10.4) are the coordinates of the point of intersection of the 2
lines.

In "Dulce et Decorum Est," what does "hag" (line 2) mean?

One of the definite strengths of this poem is the way that it
sets us up with definite expectations about what to expect because of its title, and then
presents us with the exact opposite. With such a title, we expect a poem exploring the glory of
soldiers and their bravery as they commit valiant deeds. However, note how soldiers are presented
in the first two lines of the poem:

readability="11">

Bent double, like old beggars under
sacks,

Knock-kneed, coughing like hags, we cursed through
sludge...

The brave and noble soldiers
we expect to meet are presented as dehumanised wrecks of human beings, with descriptive words
such as "old beggars" and "knock-kneed" presenting them as old men, already half-dead. "Hag" is a
term used to describe a very old woman who is normally not very attractive, so this word adds to
the presentation of the soldiers. Of course, such descriptive words help convey the theme of the
poem: that it is anything but sweet and noble to die for your country.

Given the functions f(x)=ax+b and g(x)=(1+a)x-b and (1,-2), the point of intersection of f and g lines, calculate a and b?

Since the given point is the intercepting point of the
graphs of the given functions, it's coordinates verify the expressions of the
functions.

(1, - 2) belongs to f(x)'s graph if and only
if;

f(1) = -2

f(1) = a +
b

a + b = -2 (1)

(1, - 2)
belongs to g(x)'s graph if and only if:

g(1) =
-2

g(1)=(1+a)-b

1 + a - b =
-2

a - b = -3 (2)

We'll add
(1) + (2):

a + b + a - b = -2 -
3

We'll eliminate and combine like
terms:

2a = -5

a
= -5/2

We'll substitute a in
(2):

a - b = -3

-5/2 - b =
-3

b = 3 - 5/2

b
= 1/2

The function f(x) is determined and
it's expression is:

f(x) = -5x/2 +
1/2

The function g(x) is determined and it's
expression is:

g(x) = (1 - 5/2)x +
1/2

g(x) = -3x/2 +
1/2

What indicaitions are there in Lady Macbeth's opening comments that she is not as strong?Act 2 scene 2 What line shows Lady Macbeth is fearful?...

Lady Macbeth here invokes
the forces of darkness and evil and seeks support from them so that she can appropriate
enough cruelty and remorselessness to act upon the plan of killing
Duncan.

Lady Macbeth's prayer to the same invisible forces
to turn her milk into gall and her prayer for a thick blanket of hellish darkness also
indicate that she suffers from fears of conscience. However, she makes herself fearfully
determined when she euphemistically refers to Duncan's arrival and stay at their castle
for the night :' He that's coming/Must be provided for'.

If your question relates to act 2 scene 2, the
opening soliloquy of Lady Macbeth divulges her failing strength, her fear and resistance
of conscience :
